Online Presentation
Setting up websites and buying domain names can now be done very easily online. Web pages are useful shop windows for showcasing work to a potentially large audience.
Often, it pays in the long-term to undertake short courses in web design. Alternatively, collaborate with a professional (freelance) web designer or web design student (who may work for free as part of their course) to design and set up the site.
Registering with artists' indexes or galleries can be relatively inexpensive. Axis, for example, is an online database and showcase for work. For a small fee an artist can have three photographs of work permanently 'exhibited' on their website.
